Thad ran his part of the race in 11.45 seconds, greg ran his part in 13.012 seconds and mike ran his part in 12.837 seconds. what is the difference between how fast mike and thad ran their race?

You have to subtract 11.45 from 12.837. After doing so, you get the answer of 1.387

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
